Definitions

  • the present invention relates to a coffee machine, in particular a coffee machine with devices for producing frothed milk, for example for the preparation of beverages such as cappuccino, latte macchiato or similar preparations.
  • a coffee machine comprising a body inside which is housed a brewing group for making coffee, a coffee dispenser having at least one nozzle for dispensing coffee produced by the brewing group, and a steam supply.
  • a milk container can be connected, in the lid of a frother is attached.
  • the frother is connected to the steam supply line to deliver warm milk or frothed milk from the container into a cup placed under the coffee dispenser.
  • the present invention relates to improvements to machines of the type mentioned above. More specifically, according to the invention, it is provided that the steam supply line is connected to a frother, which is held by the coffee dispenser and therefore attached to the machine, while the milk container is a tube for comprises the milk supply, which can be connected to the frother by a connection firmly connected to the frother itself and therefore attached to the coffee dispenser or held by the coffee dispenser.
  • the milk supply tube is held by the lid of the container and can thus be conveniently removed from inside the container, thereby facilitating cleaning.
  • the tube for the milk supply comprises a connection end piece, so that it can be tightly connected to the connection of the frother.
  • the milk delivery tube may be made of flexible material, such as food grade silicone rubber, extending from the container lid to the container bottom, one end of which is secured to the lid at the level of the connecting end, preferably made of a more rigid material is.
  • the lid, the connecting end piece and the hose are separable from each other or at least the hose and the connecting end piece are separable from the lid, so that a simpler and more thorough cleaning of the parts is possible, which come into contact with milk.
  • the frother comprises a passageway for entry of room air.
  • This passage can be connected to an electric valve inside the machine, which is controlled by the central unit of the machine to open and close the valve and therefore to allow or prevent the supply of air, depending on whether the user is warm or not frothy milk or warm, frothy milk.
  • the passage for entry of the room air is mounted on the frother so that an air inlet is defined directly outside the machine, whereby it is not necessary to check whether the valve is open or closed. In this way, one obtains simpler and easier-to-handle machines, although one dispenses with the possibility of producing warm, non-frothy milk, since in this case the passage for the entry of room air always remains open.
  • manual means may be provided to close the passage for the air inlet, thereby allowing the user to choose between the production of warm, frothy milk or of warm, non-frothed milk.
  • a coffee machine indicated as a whole by 1 has a body 3 in the interior of which is mounted a brewing group of a type known per se for producing coffee.
  • the brew group may be configured to be filled with loose coffee powder derived from grinding coffee beans or with single serving packages of ground coffee, for example, pads or capsules.
  • the machine 1 above also comprises a container 5 for coffee beans and is therefore particularly adapted to feed the brew group with coffee obtained by grinding the coffee beans with the internal group of meals, not shown.
  • the machine 1 has an interface 7 for inputting commands to the machine and for monitoring the progress of the brewing process of the selected beverage.
  • the machine comprises a coffee dispenser 9, which is advantageously held by a flap 11, which forms part of the front wall of the machine 1.
  • the coffee dispenser 9 in this embodiment has two nozzles 9A for dispensing the coffee-based beverage produced by the internal brewing group of the machine (not shown).
  • the shelf can be formed, for example, by a grid 13 having openings 13A for draining back-flowing liquids into an underlying tray 15 which is closed by the grid 13 and preferably fixedly connected to the flap 11.
  • the coffee dispenser 9 is combined with a frothing agent for frothing milk, which is contained in a container 17 which on the grid 13 in front of the Can be positioned flap 11 of the machine and connected to the frother, which is held by the coffee dispenser 9.
  • the container 17 is above the shelf, which is formed by the grid 13, positioned with respect to the coffee dispenser 9 at the side, since the latter has a lateral connection to the container 17 with the frother through to connect a simple lateral approach movement of the container 17 to the coffee dispenser 9.
  • the container 17 has a body 19 with a bottom 19A which is closed by a lid 21.
  • the lid 21 carries a connecting end piece 23, with which a part of the milk supply tube 25 of flexible material extending inside the body 19 to the bottom 19 A, is connected to the frother, which is held by the coffee dispenser 9 and indicated overall at 27.
  • the frother 27 includes a steam inlet port 29 that comes from a steam supply line 31 having an inlet end 31A that can be connected to a steam supply circuit inside the machine 1, which is not shown.
  • the steam is generated by a boiler or a superheater inside the machine 1, which is also not shown.
  • the steam supply line 31 is advantageously fixed to a housing 33 in which the nozzles 9A are designed to deliver coffee, which are connected to the brewing group inside the machine via a connection 35 (see the detail in FIG Fig. 3 and 5 ).
  • the complex of the housing 33, the steam supply line 31 and the frother 27 is enclosed in a box, which in Fig. 1 and 2 is visible and has been removed in the remaining figures to represent the nature of the frother 27 and the coffee dispenser.
  • the inlet opening 29 for the steam which is supplied through the steam supply line 31, opens into a first chamber 41, which is formed in a block 43 which is part of the frother 27.
  • the chamber 41 is in fluid communication with a venturi 45 formed in a second block 47 which is connected to the block 43, with seals 49 possibly placed therebetween.
  • the Venturi tube 45 terminates with a nozzle 51, via which the steam is introduced into a suction chamber 53, which is formed between the block 47 and a main body 55 of the frother 27.
  • the suction chamber 53 is in fluid communication via a passage 57 with a port 59 of the frother 27, into which the connecting end 23 of the milk container 17 is inserted.
  • a seal 61 guarantees the tightness between the port 59 and the connecting end piece 23. Die Configuration of the seal 61, the port 59 and the connection end piece 23 is such as to leave a through-hole 63 for the entrance of room air to the suction chamber 53.
  • the end piece 23 has a groove 23A, which forms a narrow passage for the air, which opens into the passage 57, which forms a VoraufMumproving.
  • the suction chamber 53 extends into a conduit 69, which opens into an end chamber 71, which allows the passage of the foamed milk down through passage openings 73.
  • the through-holes 73 are aligned vertically downwards and approximately parallel to the nozzles 9A for dispensing coffee and form a small beak for dispensing foamed milk.
  • a different number of through holes may be provided for dispensing milk.
  • the device described so far functions as follows: If the user wishes to prepare a cup of coffee or an espresso, he gives the machine 1 via the interface 7 the necessary instructions which solely activates the internal brewing group to deliver the coffee via the dispensing nozzles 9A, 9B. In this case, no steam is generated.
  • the machine 1 supplies high-temperature steam at a corresponding pressure to the opening 29 via the steam supply line 31.
  • the steam flows via the venturi 45 into the suction chamber 53, in which the venturi action is due to the supply pressure of the steam from the machine to the foaming group 27 lower pressure than the room pressure is generated.
  • the low pressure generated in the suction chamber 53 leads to the suction of the milk via the milk supply pipe 25 with its end piece 23 and simultaneously to the suction of air through the air passage opening 63 and a groove 23 A of the end piece 23.
  • the VoraufCum screening 57 which sucked from the container 17 frothed cold milk with room air coming from the passage 63.
  • the foamed mixture of milk and air sucked into the suction chamber 53 is brought to temperature by contact with the steam coming from the machine, which causes the Evaporative heat to the milk-air mixture gives off and condenses.
  • the so-frothed warm milk is delivered via the passage 69 and the openings 73 in the cup, which the user has placed on the grid 13 below the coffee dispenser 9.
